How can I get access to the build?

Few hours before RC will appear for download, I would like to post short summary in a form of Q&A.

A:  TechNet and MSDN subscribers will have access to the build on those websites close to April 30th.   MVP can also download the build from Connect on April 30th.  All others can download the RC on the Microsoft Download Center on May 5th.

Q:  How big is the Window 7 RC download?

A: The x86 version of Windows 7 RC is approximately 2.47 gigs. The x64 version is approximately 3.2 gigs.

Q:  Will the RC code be download-only, or can I have physical media mailed to me? 

A:  The Windows 7 RC code will only be available for download. 


Q:  Will my product key from Beta work for the RC, or do I have to register to get a new one?

A:  No – you will need to register for a new PID in order to run RC.


Q:  Is there a cap to the total number of downloads for Windows 7 RC?

A:  There is no limit to the total number of downloads for Windows 7 RC.

Q:  Will Windows 7 RC be available in both 32-bit and 64-bit?

A:  Yes.


Q:  Is there a choice of SKUs for Windows 7 RC, or is it only available in Ultimate like the beta?

A:  There is one release candidate release, with all the capabilities of the Windows 7 Ultimate SKU. 


Q:  When does this build expire?

A:  Windows 7 RC will expire on March 1, 2010 – at this time the system will reboot every two hours. The license of windows 7 RC will expire June 1, 2010.

Q:  Where should I submit feedback on Windows 7 RC?

A:  The Beta testing has completed, and the release candidate is the time for customers and IT professionals to really start kicking the tires in terms of application compatibility, drivers and devices.  We will of course continue error monitoring, but application compatibility issues should be reported to the ISV.


Q:  What tools and resources are there available for IT pros to begin testing and deploying Windows 7?

A:  There are many tools available for IT Pros to begin their testing and deployments, including the Windows Automated Installation Kit, the Application Compatibility Toolkit and the Deployment Toolkit.  More information about these tools can be found at


Upgrade Experience

Q:  How does Microsoft recommend I install RC?  

A:  To install the Windows 7 RC, users will be required to either upgrade from a Windows Vista image, or do a custom (clean) installation.  Windows 7 Beta users will need to do a custom (clean) installation. 


Q:  Why isn’t there an easy way for me to upgrade from beta to RC?

A:  Upgrading from one pre-release build to another is not a scenario a real-world customer will experience.  We want our testers to experience real-world setup to provide us with real-world telemetry as we work on finalizing the product.


Q:  Is there a smooth upgrade from Windows XP to Windows 7?  

A:  As a result of the many changes we’ve made to the operating system, users who wish to upgrade from Windows XP to Windows 7 on the same computer will need to perform a custom (clean) installation.

Q:  Does Microsoft provide any guidance on how to transfer files and settings from a previous operating system to Windows 7 when a clean installation is required?

A:  Tools, guidance and other resources are available on to assist in the upgrade process.  Microsoft also provides a special utility on the release candidate CD to assist users with identifying, backing up and transferring files and settings to Windows 7.  For more information on the Windows Easy Transfer utility please visit

Hello Damir,

here are some additional information’s about the RC installation:

-it is possible to use your public beta key for activating this release candidate

-by deleting the ei.cfg on the ISO you will be able to choose the edition during the installation

-a fresh install is always recommended but it is possible to update your beta to the RC, you need only to patch the cversion.ini on the ISO, edit the MinClient value to 6999.0
